Advise needed for Static vs Dynamic linking
c++, dll, python, static-libraries
Solution
It depends on your desired deployment. If you use dynamic linking will need to carefully manage the libraries (`.so`, `.dll`) on your path and ensure that the correct version is loaded. This can be helped if you include the version number in the filename, but then that has its own problems (security... displaying version numbers of your code is a bad idea). Another benefit is that you can swap your library functionality without a re-compile as long as the interface does not change.
Statically linking is conceptually simpler and practically simpler. You only have to deploy one artefact (an `.exe` for example). I recommend you start with that until you need to move to the more complicated shared library setup.
Edit: I don't understand your "extra credit" question. What do you mean by "edit values"? If you mean can you modify variables that were declared in your C++ code, then yes you can as long as you use part of the public interface to do it. BTW this advice is for the general decision. If you are linking from Python to C/C++ I think you need to use a shared library. Not sure as I haven't done it myself.
EDIT: To expand on "public interface". When you create a C++ library of whatever kind, you specify what functions are available to outside classes (look up how to to that). This is what I mean by public interface. Parts of your library are inaccessible but others (that you specify) are able to be called from client code (i.e. your python script). This allows you to modify the values that are stored in memory.
If you DO mean that you want to edit the actual C++ code from within your python I would suggest that you should re-design your application. You should be able to customise the run-time behaviour of your C++ library by providing the appropriate configuration.
If you give a solid example of what you mean by that we'll be able to give you better advice.
Problem
I have a Python code that needs to be able to execute a C++ code. I'm new to the idea of creating libraries but from what I have learned so far I need to know whether I need to use static or dynamic linking. I have read up on the pros and cons of both but there is a lot of jargon thrown around that I do not understand yet and since I need to do this ASAP I was wondering if some light can be shed on this from somebody who can explain it simply to me. So here's the situation. My C++ code generates some text files that have data. My Python code then uses those text files to plot the data. As a starter, I need to be able to run the C++ code directly from Python. Is DLL more suitable than SL? Or am I barking up the completely wrong tree? Extra: is it possible to edit variables in my C++ code, compile it and execute it, all directly from Python?
